Opis:: The problem of energy saving resources is now very urgent. Reducing the lighting electricity consumption through the introduction of advanced technologies is one of the most effective ways. The main method - the replacement of incandescent lamps with LED lamps, since the light output of the latter is 5-8 times higher. However, LED bulbs are only becoming widespread, as most products entering the Ukrainian market are of low quality and of high cost. Also, the frequent phenomenon is the submission by producers of false information about the characteristics of the lamps. There fore, we decided to experiment with the light bulbs available in the market of the western Ukraine. Many people think about changing the traditional incandescent lamp-lamp to some thing more perfect, since the prices for electricity are constantly growing, because their efficiency is very low and is only 5%. Among alternative way so flighting, halogen lamps are one of the options.

Opis:: In this article we consider the questions of studying the characteristics of modern light sources on the example of LED lamps (LED). The problem of energy savings gained weighty significance in recent years, particularly in the light. In many developed countries as a way to reduce power consumption the replacement of incandescent lamps to LED is considered. LED are advanced energy efficient lamps, but much of the lamps that are coming on the inner market of Ukraine do not correspond to the declared lighting and electrical parameters. That is why we investigated LED lamps of such brands as «AUKES», «OK», «Iskra», «Lemanso» if they are in accordance with lighting and electrical parameters. The results of the study indicate that among the investigated parties of lamps value for active power of all the producing capacity does not meet the stated on the package. On the basis of experiments we also determined the dependence of illuminance E, Lx of voltage U, V. On the basis of this study we can say that most of LED lamps when changing the voltage in the range of 180 -240 V LED illumination is proportional to approximately 1% ( ± 0,2%) with a change in voltage at 1%. As we have seen from the research the alleged power LED lamps does not match the experimental data, in some cases more than 30% - LED (AUKES). A major drawback of LED, that enter the market in Ukraine is a low power factor, which varies between 0,51-0,63 further reduces technical and economic parameters of power supply and increases electric gates.
